whenever you are."

"About half an hour then."

He retired to the room upstairs, partly for the purpose of exchanging
his coat, but also half tempted to make a hasty examination of the
valise which Coolidge had thoughtlessly left overnight in the closet.
The conception had already taken strong hold on his mind that his
visitor of the evening before had been the mysterious impersonator of
Natalie Coolidge; and that she had come there with some deliberate
purpose--no-doubt a secret conference with Percival. If her resemblance
to the mistress of the house was as remarkable as he had been led to
believe, her entrance to the place would be comparatively easy of
accomplishment, and the danger of discovery correspondingly small. It
never occurred to him to question Natalie's story. To be sure there were
details he found it difficult to fully accept as true, but the girl
certainly believed all she had told him. She denied earnestly having
been the one invading his room, and he believed her implicitly; yet the
person who had visited him was so closely her image as to make it still
seem almost an impossibility that she could be a separate individual.
Nothing less than Natalie's own word would have brought conviction. And
this person had supposed she was visiting the apartment occupied by
Percival Coolidge. This was the only satisfactory explanation of her
presence there; whether she came that night for the first time, or as a
supplement to other similar visits, it was unquestionably Coolidge
